Summary of specifications for EX10 and D10

• Unique electronic-controlled extremely reliable switch design.
• Unique Infinitely Variable Digitally-controlled Brightness System.
  (100 levels of output!)
• Piston Drive (PD) design makes the light more compact than lights with traditional clicky switches.
• Switch reliability is greatly increased over traditional switches.
• Electronically controlled switching - no spark generated from the piston contact since the microprocessor switches on the light AFTER the piston makes contact. This eliminates the risk of explosion in a flammable environment!
• Electric current passes through the piston on the INSIDE of the light. No current is passed through the outside shell, which is hard-coat anodized.
• When the light is off, the microprocessor draws very, very little power - between 0.1-0.4ma (0.2ma typical). For example, one 2000mah cell would last about 416 days!
• Instant access minimum & maximum brightness - very simple user interface.
• Extremely compact size and lightweight suitable for Every Day Carry (EDC).
• As with all NiteCore products, they use tough, imported 7075
  military-grade aluminum!
• Mil-Spec Type III Hard Anodized finish - no bare aluminum exposed, making it more durable.
• Aggressive knurling over most of the surface - maximizes grip.
• Resistant to impact from dropping in accordance with US MIL-STD-810F.
• Waterproof to IPX-8 standard.
• Broad-voltage fully regulated circuit, compatible with standard primary batteries as well as protected li-ion cells
• Uses a highly efficient Cree XR-E Q5 WC LED lamp.
• 130 lumens at maximum output.
• Extended runtime on low (3-5 lumens)
• Metal reflector with optical grade coating.
• Impact-resistant optical lens with anti-reflective coating on both sides
• Tactical lanyards braided with military-grade 550 parachute-cord.
• Able to tail-stand to act as a candle.

The EX10:

• Uses CR123A's as well as protected lithium-ion RCR123A's!
• Stainless steel retaining ring in bezel.
• Dimensions: 77mm x 21.5mm or 3.0in x 0.85in (length x diameter)
• Weight: 35g or 1.2oz (without batteries)
• Runtimes on CR123A (until 50%)
  Max: 130 lumens, 110 minutes
  Min: 3 lumens, 65 hours or 2.7 days!
• Runtimes on RCR123A (protected only)
  Max: 130 lumens, 80 minutes
  Min: 5 lumens, 60 hours or 2.5 days!
